AI-infused German Engineering

From CAD design to CFD, from cooling to combustion, from DoE to machine learning and AI – we got you covered.

CAD-Design

High-precision 3D models for components and assemblies. Your path from first concept to production-ready product. Our focus: maximum functionality, optimal manufacturability, and efficient development processes.

Rapid Prototyping, 3D Scan & 3D Print

From idea to prototype in record time. With 3D scanning, reverse engineering, and industrial-grade 3D printing, we deliver functional results, fast, precise, and ready for validation and further development

3D-CFD

We make the invisible visible: high-resolution flow and thermal simulations for both static and moving geometries. Our 3D-CFD analyses uncover optimization potential, pressure losses, hotspots, flow disruptions, and emission issues, long before physical prototypes are built.

Hydrogen Engine Development - H2ICE

The catalyst for the powertrains of tomorrow, we convert combustion engines for hydrogen operation, from component selection and H₂-specific combustion simulation to full test bench validation. Our deep expertise in charging systems, fuel injection, simulation, and emissions control makes us an enabler of an emission-free engine future.

Innovation Consulting

Innovation is no longer optional – it must be continuous. But without the right systems, it drains time and resources.



Felsaris is your innovation partner. We make innovation repeatable and manageable by combining structured creativity, focused workshops and ZIM funding expertise to turn ideas into commercially viable solutions.



We turn vision into results and innovation into advantage.

Up to 360,000€ funding for your R&D projects.
ZIM R&D Funding

ZIM Funding Application Support

We guide you through the entire ZIM application process - from idea validation to final submission. With technical expertise and clear communication, we maximize your chances of approval and help secure funding for your innovation project.

Innovation Workshops

Innovation doesn’t happen by chance. Our focused workshops help you develop innovative product ideas and explore new markets that match your skills. In partnership with top innovation consultancies, we bring expertise from both mechanical engineering and IT.

Strategic & Structural Innovation Consulting

We support organizations in developing and implementing innovation strategies, guiding projects from idea to application. Additionally, we help establish the structural foundations needed for sustainable innovation success.

AI in Engineering

We bring AI into your engineering processes - fast and hands-on. Whether it’s smarter design, faster simulations, or better decisions through data and surrogate models, we help you find the right use cases and turn them into real results.

FAQ

Which industries does Felsaris serve?

We focus on sectors where flow, heat transfer, cooling, or combustion are critical. Our expertise spans mechanical engineering, automotive, aerospace, and energy technology. We also support emerging fields such as hydrogen combustion with tailored solutions.
Result:
Reliable support across demanding industries and a clear innovation edge.

What does a typical engineering service look like?

We start with a consultation, define your requirements, and set clear technical goals. From first sketch to functional prototype, we apply our engineering expertise with targeted design, simulation, and optimization. For urgent needs, our CAD and CFD on-demand services provide flexible support without long lead times.
Result:
Engineering that accelerates your projects, reduces costs, and gives you a clear technological advantage.

Can you develop a functional hydrogen combustion engine (H2ICE) for us?

Yes – this is our core expertise. We have long-standing experience in developing hydrogen internal combustion engines across all classes, up to powerful V8 units, for both stationary and mobile applications. A particular focus is on high-performance passenger car powertrains with up to 600 hp. Starting from a conventional base engine, we design the complete H₂ powertrain: mechanical conversion, performance and emissions layout, boosting systems, test bench validation, and precise calibration for your prototype vehicle.
Result: A hydrogen engine that raises performance and efficiency to a new level and secures your edge in a market that is being redefined right now.

Can you help me develop an innovative ZIM project idea?

Yes – we support you from the first idea to the finished application. In a structured innovation workshop, we map your capabilities, apply proven creativity methods, and analyze market potential to shape a forward-looking project. The workshop itself is already eligible for 50–80% public funding, and we prepare your complete ZIM proposal afterwards.
Result:
A fundable project idea that becomes an innovation venture and strengthens your market position long term.

What is the real benefit of simulations?

They speed up development, cut costs, and improve quality. Simulations provide critical insights early on – before expensive prototypes or tests are needed. They also deliver a deep understanding of flow, heat, and structural behavior. Based on these results, we can even build predictive AI models to support future design decisions.
Result:
Products that reach the market faster, cost less, and stay one step ahead technologically.

Simulations are usually too expensive for small companies. What makes your service different?

We ensure every simulation delivers clear value. That means we only run them when the benefit outweighs the effort. Your first consultations are free and give you a transparent view of the expected ROI. For predictable costs, we also offer fixed-term CFD on-demand subscriptions that minimize risk and keep expenses under control.
Result:
Simulations that pay for themselves and give your project a measurable technological edge.

What is the ZIM funding program?

ZIM (Central Innovation Program for SMEs) is Germany’s most important funding program for small and medium-sized enterprises. It supports innovative R&D projects with grants of up to €360,000 – covering personnel costs, external services, and project-related overheads.We help you develop a suitable project idea and handle the entire ZIM application process for you – from the first concept sketch to final approval.
Result:
Maximum funding for your innovation – and a clear edge in bringing your ideas to life.

Can your consulting services be subsidized?

Yes – our consulting services are accredited under the BAFA Innovation Voucher Program. This gives you up to €3,500 per project (up to 80% in Eastern Germany), twice a year. In total, you can secure up to €7,000 in consulting annually while only investing €3,500 yourself. We also manage the entire BAFA application so you get the maximum support with no administrative effort.
Result:
High-quality innovation consulting at half the cost and a direct boost to your competitiveness.
